CAN Communication problem

Using Arduino Networking, Protocols, and Devices
1

Hey guys,

I recently purchased the CAN-BUS shield v1.2 from seeeduino and mounted it on top of my Arduino Uno. The code runs fine but whenever I read the ID that was sent "CAN.sendMsgBuf(0x190,0,0, 3, Readtag);" I receive 90, totally ignoring the first number, as if the limit is 255 or 0xFF. Anyone has gone through anything similar?

Thanks in advance!

#include <mcp_can.h>
#include <SPI.h>

MCP_CAN CAN(9);   
     
unsigned char Length = 8;
unsigned char ID;
unsigned char buffer;
unsigned char Storage[8]; // Stored values are in Hex format
unsigned char Readtag[3] = {0xE4, 0x00, 0x00};
int i = 0;


void setup()
{
 Serial.begin(57600); //Set Baudrate for Arduino-Computer interface
Stage: 
 if(CAN_OK == CAN.begin(CAN_100KBPS))                   // init can bus : baudrate = 100k
    {
        Serial.println("CAN BUS Shield initialisation successful!");

  }
    else
    {
        Serial.println("CAN BUS Shield initalisation failed!");
        Serial.println("Initalising CAN BUS Shield again");
        delay(100);
 goto Stage;
        
    } 

}
        
        
 





void loop()
{
  delay(5000); //time to allow myself to open serial monitor
        
 CAN.sendMsgBuf(0x190,0,0, 3, Readtag);
         CAN.readMsgBuf(&Length, Storage);      
//        if(CAN_MSGAVAIL == CAN.checkReceive())
          ID = CAN.getCanId();
        Serial.println(ID);
      for (i=0; i<8; i++){
       Serial.println(Storage[i], HEX); 
      }
       delay (5000);
        }

It turns out that I was simply displaying my ID with unsigned char which limited it to 255. i.e just changed the unsigned char ID; to unsigned long ID.

Although I doubt anyone making a simple mistake as me, but for clarification thought I should post my "fix"
